We investigated whether microalgae or linseed supply during the early postpartum period affects ovarian restimulation and supports the first postpartum ovulation in lactating anovulatory goats. Thirty-eight An-glo-Nubian-crossbred adult goats were allocated into three groups: con-trol diet (n=12), fed a total mixed ration (TMR) comprising chopped elephant grass and concentrate; algal diet (n=13), fed TMR+green microalgae (1% dry matter); and linseed diet (n=13), TMR+linseed (12% dry matter). Supplements were furnished from the 2nd to 5th week (time of weaning). Goats were estrus synchronized on day 40 by insertion of an intravaginal CIDR device for 5 days, after which 0.075mg PGF2α was applied to in-duce ovulation, and estrus was monitored for 72 hours. From the 5th-15th day of ovulation induction, the corpus luteum (CL) area and progesterone rate were monitored. The algal and linseed groups showed lower feed intake (P<0.001) and higher (P<0.001) triglyceride levels/follicle numbers, respectively. After estrus induction, no differences were ob-served in estrus response; however, the linseed group showed more and larger growing follicles (P=0.016 and P<0.01), a higher ovulation rate (P<0.05), larger CL area (P<0.05), and higher progesterone levels (P<0.001). Linseed after delivery stimulates follicular growth before and after ovulation induction, favoring better CL quality during the first ovulation.
